HI, this is my first post, though i have been lurking around the forum for bit.
Firstly, apologies if this has ben asked before, i'm sure it has but i can't find a solution in the forum.
I bought a Bresser messier 8 Inch on a Dobsonian mount earlier in the year. Initially i could not achieve focus with it then noticed it had another tube in the box, i believe its called a draw tube. Once i fitted it i could achieve focus.
A month or so i bought an eq6 mount which i'm controlling with stellarium, A week ago i bought a Canon 60d DSLR and a T mount. Initially i could not achieve focus. Checking around the forum indicated that the issue was caused by the camera not being close enough so i removed the draw tube and i can now focus the camera. The problem i am now having is that when i start the telescope I need to star align the telescope, i can't get a live feed through the camera to show any stars (not sure if i should be able to) so i need to fit one of the eyepieces to centre on the selected star. I can't now achieve focus as the eyepiece is too close. I could attach the draw tube to align and then remove it to fit the camera, but i don't really want to do that in the dark.
I'm thinking that an eyepiece extender might fix this issue though i'm not sure, i've unscrewed the lens out of 2x Barlow and tried to use that to extend the distance to eyepiece but that hasn't worked.
Any advice woul dbe gratefully and thanks in advance
Dean
